Ford Motor Company / lug nuts

Over my last 4 oil change and tire rotation appointments I have had to have at least 4 lug nuts cut off in order to do a tire rotation. 19-20 lug nuts over the past 8 months.
It is getting quite expensive. Isn't there something you can do about the material being used to produce them? I am on a fixed income and cannot afford to have 4-5 Lug Nuts cut off every visit. The latest incident was today 11/12/2018.
